These NYU robot fish developed by the Polytechnic Institute of New York University would potentially benefit underwater fish and other creatures by leading them away from danger, like the oil spill in the Gulf of Mexico.

The idea is that real fish would actually be likely to follow some of these NYU robot fish in schools, where the robot fish can lead the real fish away from danger zones. The NYU robot fish are still in the very preliminary stages of development, but this type of technology is very likely and could save affected wildlife.
